Richard Baxter, the renowned Puritan pastor, spoke of his own conversion in the following way:
The same things which I knew before came now in another manner, with Light,and Sense and Seriousness to my heart.
It seems to me that this ought to be the sentiment of most believers who grow up in a Christian home and who are brought up in a church that preaches the gospel. It's not so much that in conversion they are learning new truth as it is that the truth they know affects them in a new and profound way.
